fbdev: omapfb: Drop unused remove function

[ Upstream commit fc6699d62f5f4facc3e934efd25892fc36050b70 ]

OMAP2_VRFB is a bool, so the vrfb driver can never be compiled as a
module. With that __exit_p(vrfb_remove) always evaluates to NULL and
vrfb_remove() is unused.

If the driver was compilable as a module, it would fail to build because
the type of vrfb_remove() isn't compatible with struct
platform_driver::remove(). (The former returns void, the latter int.)

While it doesn't hurt to backport this patch, I guess it also doesn't give any benefit (apart from increasing my patch count in stable :-).

This commit just removes code that was thrown away by the compiler before. So I'd not backport it.

Ack, dropped. Thanks!
